ContextNodeBase.SubNodes 属性

获取 ContextNodeBase 对象的直接子级。

命名空间：  System.Windows.Ink.AnalysisCore
程序集：  IACore（在 IACore.dll 中）

语法

声明
Public ReadOnly Property SubNodes As ContextNodeBaseCollection
用法
Dim instance As ContextNodeBase
Dim value As ContextNodeBaseCollection

value = instance.SubNodes

public ContextNodeBaseCollection SubNodes { get; }

public:
property ContextNodeBaseCollection^ SubNodes {
    ContextNodeBaseCollection^ get ();
}

/** @property */
public ContextNodeBaseCollection get_SubNodes()

public function get SubNodes () : ContextNodeBaseCollection

属性值

类型：System.Windows.Ink.AnalysisCore.ContextNodeBaseCollection
ContextNodeBase 对象的直接子级。

备注

此属性只返回直接子级，而不是所有后代。

示例

此示例演示的方法递归遍历一个 ContextNodeBase 对象树。示例中使用了 SubNodes 属性，并通过添加 TreeNode 对象填充 System.Windows.Forms.TreeView。然后，将这些树节点的 Text 属性设置为 ToString，从而添加已识别字符串或形状名称（如果合适）。

Private Sub WalkTree(ByVal parentContextNode As ContextNodeBase, ByVal parentTreeNode As TreeNode)

    Dim cNode As ContextNodeBase

    For Each cNode In parentContextNode.SubNodes

        Dim newTNode As New TreeNode(cNode.ToString())

        If cNode.Type = System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkWord AndAlso _
           cNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.RecognizedString) Then

            newTNode.Text = newTNode.Text + _
                ": " + CType(cNode.GetPropertyData(PropertyGuidsForContextNodesBase.RecognizedString), _
                String)

        ElseIf cNode.Type = System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkDrawing AndAlso _
               cNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.ShapeName) Then

            Dim shapeName As String = CType(cNode.GetPropertyData(PropertyGuidsForContextNodesBase.ShapeName), _
                String)

            If shapeName <> "" Then
                newTNode.Text = newTNode.Text + ": " + shapeName
            End If

        End If

        WalkTree(cNode, newTNode)
        parentTreeNode.Nodes.Add(newTNode)

        ' Add the context node as a tag of the tree node
        newTNode.Tag = cNode
    Next cNode

End Sub 'WalkTree

private void WalkTree(
    System.Windows.Ink.AnalysisCore.ContextNodeBase parentContextNode, TreeNode parentTreeNode)
{
    foreach (ContextNodeBase cNode in parentContextNode.SubNodes)
    {
        TreeNode newTNode = new TreeNode(cNode.ToString());
        if ((cNode.Type == System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkWord) &&
             cNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.RecognizedString))
        {
            // Get the recognized string
            newTNode.Text += ": " +
                (string)cNode.GetPropertyData(PropertyGuidsForContextNodesBase.RecognizedString);
        }
        else if ((cNode.Type == System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkDrawing) &&
                  cNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.ShapeName))
        {
            newTNode.Text += ": " +
                (string)cNode.GetPropertyData(PropertyGuidsForContextNodesBase.ShapeName);
        }
        WalkTree(cNode, newTNode);
        parentTreeNode.Nodes.Add(newTNode);

        // Add the context node as a tag of the tree node
        newTNode.Tag = cNode;
    }
}
